开发利用海水化学资源是缓解陆地矿产资源危机的有效途径,功能分离材料则是海水化学资源高效提取的关键。重点介绍了以离子交换膜、离子筛和吸附剂为代表的功能分离材料及其在海水制盐和海水提取钾、锂、铀的应用现状,并对其发展趋势进行了展望。 Exploitation and utilization of seawater chemical resources is an effective way to alleviate the crisis of terrestrial mineral resources. Functional separation materials are the key to the efficient extraction of seawater chemical resources. The functional separation materials such as ion exchange membranes, ion sieves and adsorbents, as well as their applications in the salt water and seawater extraction of potassium, lithium and uranium were introduced. The development trend was also prospected.
